IMPROVEMENT IN PLOWlNG-IVIACHINES.

Specification forming part of Letters Patent N o. 19,2!5, dated January 26, 1858.

To all whom-it they concern Be it known that I, WILLIAM STODDARD, of Lowell, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Plowing- Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference .being had to the accompanyingdrawings, and to the letters of reference marked thereon.

In referring to the drawings, Figure 1 denotes an inverted plan or under side view of my machine; Fig. 2, a like inverted end elevation of it; Fig. 3, a side elevation of the same when placed upright and in a working position.

The nature of my invention consists in so constructinga series of plows, with adjustable gage-pulleys connected to the mold-board thereof, as described, for governin g the desired depth of furrow, and connecting these plows firmly to endless bands or chains, which are carried by, combined with, and connected to swinging arms and pulleys thereon in such manner that the plows are moved to turn the furrows, and at the same time a constant yielding movement is given the plows, as described, while and at the same time the plows are governed to the required depth and to a uniform depth invall uneven or even surfaces of the ground, while they are operated to turn the furrows at right angles with themachine; also, in the arms carrying the plows, which, in addition to their self-adj ustment vertically, have a secondary adjustment, whereby they and the plows can be instantly lowered to or raised from the ground for any desired purpose by the operator, these several parts being relatively arranged with each other and the other parts ot' my machine for operation, all substantially as hereinafter Set forth.

To enable persons skilled in the art nearest to which my invention appertains to construct and carry out the same, I will describe it as follows:

I ,construct a carriage or platform of wood, (seen at A in each of the several figures ofthe drawings,) which is supported and carried by four wheels, M and M2, and which carriage in turn carries or sustains all the other parts of my machine. The smaller or forward wheels, M2, are fitted so as to revolve freely-upon an axle, r, Figs. land 3. This axle swings upon the king-bolt or` trunnion N2, which passes through its center, and is rmly secured to the under and forward portion of the carriage A.

. boxes is fitted the axle or shaft seen at c, so

as to turn freely therein. To each outer end of this shaft thelarger or hind wheels, M, are firmly secured for sustaining and carryingjointly with the wheels M2l the carriage A and the parts connected thereto.

I construct a driving-shaft, (seen at 0,) to which motive power may be applied by windmillB vor otherwise, for the operation of my machine. The upper portion of this shaft C turns in the stand Q2 and its lower end in the platform A. Onand near the lower end of this shaft I secure a bevel-pinion, d, which meshes with and turns the bevel-gear E, of a larger,

diameter, which is fitted to turn freely on the axle c, and prevented from moving laterally' thereon by the rings ct a, which are secured to the shaft c.

A clutch (seen at D) is fitted to slide on the shaft c, and prevented from turning, except with the shaft, by a spline, V2. This clutch is operated by lever F, the lower end of which is fitted to the groove R2 in it, and the upper end of which is pivoted so as to swing on'the stand g. It is moved by a reach, H, connected to the lever Gr, to connect the clutch D and shaftc with the bevel-gear E, in order that the driveshaft C may turn them and the wheels M thereon to move the machine'about quickly, or for locomotion when the plowing is not being performed.

I will now describe the parts for effecting the plowing 3 and immediately in connection therewith I construct a shaft (seen atp, Fig. l) and suspend it so that 011e of its ends will freely turn in the stand S2, which is secured to the under side of the carriage A, andthe other end in the lever Gr. On the shaft p a pulley, P, and

abevel-gear, O, are secured, which are driven or revolved by the shaft C and bevel-gear E, which meshes with it.

I construct a shaft (seen at N) and suspend it so as to freely revolve in the stands T2, which are secured to the under side of the carriage A, Figs. 1 and 2. To' this shaft N a pulley, P2, is secured for driving one'series of plows on One side of the machine, and which is itself driven by belt T from pulley P.

I construct a shaft, (seen at L,) one of its ends being suspended so as to freely turn in the stand V2, secured to the under side of the carriage A, while its other end is suspended in the I end of the lever G, which has its fulcruin or turning-point ou the stud A2, which is secured to the stand W2, and this stand to the carriage A.

A worm-gear, Q, Fig. 2, is firmly secured to the shaft c, and into this wOrm-gearQ the worm K is meshed or connected by movement ofthe leverGfor moving along the carriage and plows the width of a furrow onto land, and then, by a contrary movement of the lever G, the worm K is disconnected from` thewormlgear Q, and

l the carriage remains motionless until the next `furrow is formed at right angles with the machine, and so on. 4

The lever Gr is connected to the lever F by the reach H, so that when this lever Gris moved to connect the worm K and worm-gear Q and the bevel-gear O with the bevel-gear E thelever F will previously unclutch the clutch D i from the gear E, or when the leverF is moved to connect the clutch D with the gear E the worm-gear Q, worm K, and bevel-gears O and E are disconnected previously to preventbreaking the machine. I place a pulley, P3, on the shaft L, which is driven by a cross-belt, V, for

y operating the plows in a proper direction. An-

- other'pulley, P4,`is connected to the shaft L,

A with the carriage A, s0 as to be self-adjustable to swing freely up and down, (without loosening the belts Or chains,) to cause the plows to sink to the same or a uniform depth in the ground if its surface be regular or irregular.

To the Outer end of each arm J a pulley, R, is fitted so'as to revolve freelytherein. Around these pulleys R and the pulleys P2 and P4 endless belts or chainsW are placed, and propelled by the connection with and turningof the shaft C by any practical motor.

It will be seen that 011e of the belts W on one side of my machine passes around and is driven by the pulley P2, while the other passes around and is driven by the pulley P4. (See Fig. 1.) I now construct a number of plows, X, and secure them firmly to the belts Or chains W, and provide them with an adjustable crank-shaft, s, passing through the mold-board, and on each side Ot' which I place gage-pulleys e, which can be raised or lowered on the mold-board by the adjustable crank-shaft s, held by set-screws, to give any desired and uniform depth of furrow on even or uneven ground by means of both these adjustable gages e and s and the arrangement of plows X with the armsJin such manner, as within described, that they will at the same time yield of themselves to any inequalities ofthe ground.

I construct a windlass (seen atm) and place it upon the top ofthe platform A. This windlass is connected with the outer ends of the arms J by the cords i, so that the plows X can' all be instantly raised either out ofthe ground or lowered into the ground by turning the Windlass crank, which is under the control of the Operator, all as hereinbefore set forth.

What I claim as my invention, and desire to secure by Letters Patent, isp Constructing the plows X with an adjustable depth-gage, e and s, attached to themoldboard thereof in the manner described, when such plows are connected (for operation) to an endless chain or band, in combination with the flexible arms J, which carry the plows X and band W, essentially in the manner and for the purposes fully set forth and described.

WILLIAM STODDARD.
